Definitions

• the present invention relates to the cooling of hot molds, and more specifically to a system for cooling hot molds of glassware forming machines
• U.S. Patents 1,875,202; 3,355,277; 4,251,253 and 4,502,879 relate to providing a plurality of axial passages in the body of the mold halves and the introduction of an air flow through said passages from the bottom or from the top of the mold.
• the temperature control must be very precise, that is, it is very important to maintain the isotherms of the light bulb side to maintain an ideal thickness distribution for The whole container.
• Any variation of temperature in the mold implies that, if some sections are more trias, the glass will be thicker in those parts and, if it is hotter, it will become thinner. Excessive temperatures in any region mean that the parison is not rigid enough for investment and deposit on the mold side so the preform can deform and get out of control.
• European Patent No. EP0612699 by Richard Kirkman which refers to an apparatus for cooling molds comprising a pair of complementary mold arms, each arm supporting mold halves in such a way that when the arms move towards each other, the mold halves form a plurality of cavities.
